Filed Apr. 30, 1968, Ser. No. 725,393 Int. Cl. B65d 67/02 US. Cl. 2481016 Claims ABSTRACT OF THE DISCLOSURE A refuse sack holder for use withdisposable bags. The holder supports a disposable refuse sack in an openposition so that it may be filled with refuse. The holder has associatedclamps which hold the bag in position and a swingably mounted lid tocover the open mouth of the bag held.

This invention relates to refuse handling, and more in particular tosupporting paper sacks or the like during the time that they are beingfilled with refuse.

An object of this invention is to provide a disposable refuse sackholder that can be easily and efiiciently used.

A further object is to provide such a holder that is sanitary andeconomical.

A still further object is to provide means by which containers that havebeen filled with refuse can be quickly and efiiciently removed andreplaced with empty containers.

These and other objects will be in part obvious, and in part pointed outbelow.

In the drawing:

FIG. 1 is a perspective view of one embodiment of the invention;

FIG. 2 is a view similar to FIG. 1 showing the holder without the refusesack;

FIG. 3 is a vertical section on the line 3-3 of FIG. 2, showing one ofthe clamps of the unit in FIG. 1 with clamp in the sack-releasingposition;

FIG. 4 is a view similar to FIG. 3, with the clamp in the bag-holdingposition and with the cover closed.

Referring to FIG. 1 of the drawing, a disposable refuse sack 2 is heldin a position to receive refuse by a supporting unit 4, which is mountedon a wall by a sheet metal supporting bracket 6. Sack 2 is a multi-plykraft paper sack with one ply made of treated paper, and the sack isstrong and resistant to moisture. Supporting unit 4 comprises arectangular frame 7 which surrounds a rectangular opening 8 (see FIG.2), which is defined by four vertical walls 10. Flared outwardly fromthe bottom of walls 10 and integral therewith is a frustoconical skirt 9comprising two side walls 12 and identical front and rear walls 13. Eachof the side walls 12 (see FIGS. 3 and 4) has an integral horizontalflange 15 which rests upon a mating flange 17 of the mounting bracket 6,and each set of flanges 15 and 17 is held together by expansibleclamping plugs 19. Supporting frame 6 is attached to a supporting wall(not shown) so that unit 4 is supported above the floor a sufficientdistance to permit sack 2 to hang freely.

Mounted upon each of the walls 12 and the adjacent side walls 10 thereis a clamp 16 which clamps the top edge portion of sack 2, which hasbeen formed into a cuff 14 in a manner discussed below. Each clamp 16comprises a clamp frame 18 riveted to walls 10 and 12, and a swingingclamping member 20, which is mounted between a pair of ears 21 of clampframe 18 by a fixed axle 22. Clamping member includes a locking portion23 and an integral flat handle 24. Locking portion 23 has a curved camsurface 26 which is knurled to form a large 3,522,922 Patented Aug. 4,1970 number of small parallel ridges which extend the length of thelocking portion between ears 21. The distance of surface 26 from thecenter of axle 22 increases in a counterclockwise direction from aminimum distance at 27 to a maximum distance at 29. When clamping member20 is positioned as shown in FIG. 3 it does not project to ward wall 10beyond the edges of ears 21, and cuif 14 can be readily positioned alongwall 10 as shown. However, when the clamping member is swung clockwise(see FIG. 4) surface 26 can be moved into contact with wall 10, exceptthat when the sack wall is positioned as shown, the clamp engages thesack wall and clamps it tightly against wall 10.

In FIG. 3, the clamp is shown in the open position. Handle 24 has beenraised to the position shown, thereby turning clamping member 22 in acounterclockwise di rection until there is a space between the lockingmember and the adjacent wall 10. This space permits cuff 14 of sack 2 tobe slid into position along the outer surface of wall 10.. Handle 24 isthen moved in a downwardly direction (see FIG. 4), thereby turningclamping member 20 in a clockwise direction until it contacts culf 14and presses it against wall 10. As refuse is deposited in sack 2, theadded weight of the sack tends to pull cuff 14 upwardly along wall 10and around the upper edge of the wall. Because of the friction andclamping forces between the surface of cuff 14 and the surface 26 oflocking member 20, the upward force on cuff 14 tends to rotate thelocking member in a closewise direction, thereby pinching cufl 14 moretightly between wall 10 and locking member 20. In this manner, theclamping mechanism responds to additions to the weight of the sack to besupported by clamping the cuff of the sack more securely. When the sackis to be removed, handle 24 is raised, thereby returning the clamp tothe open position shown in FIG. 3.

Cuff 14 acts as a support for the sack; that is the cuff and theadjacent portion of the sack are relatively strong, and the sack is ofsubstantantially the same horizontal dimensions as opening 8, so thatthe sack walls and the cuff extend snugly along the opposite sides ofwalls 10. The top edges 34 of walls 10 are bent inwardly and flattenedto form an inside collar and a rounded top edge. Hence, the reverse fold36 connecting the cult to the main portion of the sack rests upon therounded wall edges and there is no substantial tendency for the roundededges to cut the sack walls. Also, cuff 14 is of substantially the sizeof walls 10 so that it holds itself against walls 10. Hence, it has beenfound that the supporting cooperation between the walls 10 and thecuffed end of the sack is sutficiently great that a pair of clamps 16,located on opposite sides of opening 8, are sufficient to support sack2, even when it has been filled with a large quantity of refuse.

A particular problem that has been encountered in past devices forhandling and supporting disposable refuse sacks is the tendency for someof the refuse deposited in the mouth of the supporting structure to notfall into the sack. The portion of the refuse remaining in or beneaththe supporting structure after the removal of the refuse sack is oftendiflicult to remove and creates an unsanitary condition. The cuffarrangement of the present invention prevents any refuse from fallingbetween the disposable sack and the inside of the supporting structure.

An additional feature of the holder, shown is a lid 27 which isswingably mounted at each of its rear corners (see FIGS. 1 and 4) by ahinge formed by a bolt 28 and a bracket 30 which is mounted upon therear portion of skirt 9. Bolt 28 extends through bracket 30 and a sideflange 31 on the lid, and a pair of friction washers 33 and 35 areclamped between the bracket and the flange. Washer 33 is fixed to thebracket, and washer 35 is fixed to the flange, so that the washers givethe hinge an antifriction characteristic. Hence, the lid may be swungtoward its vertical position and will be held there by the action of thefriction washers. As shown in FIG. 4, there is a narrow fiat strip offoam rubber 34 bonded to the bottom surface of lid 27 and extendingaround the periphery of opening 8 in alignment with the top edges 37 ofwalls 10. When the lid is closed, the weight of the lid holds it tightlyagainst the top edges 37 of walls 10, and strip 34 is compressed againstthe fold portion 36 of bag 2. which extends around the top edges 37 ofwalls 10. In that way, the lid provides a closure from the top of thebag which substantially seals it when the lid is closed, yet the lid maybe swung up and will remain out of the way for placing refuse into sack2.

In installing a sack 2 in unit 4 the top portion of the sack is foldedoutwardly and downwardly to form the cult 14 which is substantially theheight of walls 10. The sack is then positioned with its top portionwithin opening 8 and with cuff 14 above the level of walls 10. The sackis then moved downwardly and the cuff is placed outside wall 10 and thesack is further lowered until cufi 14 is coextensive with the outersurfaces of walls 10, and the fold in the sack at the top of the cuffrests upon the upper edges of walls 10.

In the illustrative embodiment, sack 2 is a disposable refuse containerwhich is inexpensive to manufacture, convenient to handle and store, anddependable in use. Such sacks may be produced upon equipment which is incommon use, and the cufi 14 may be produced at the time of installationinto unit 4. It has been pointed out that unit 4 provides a verysatisfactory support for the sacks particularly in that the array ofedges cooperates with the clamping means and the cuff construction.
